Abstract

An electrical generator assembly (32) for use in a gas turbine engine (30), which assembly includes an electrical motor (32a) configured to connect to an accessory gearbox (18) arranged radially outward of a main axis of the gas turbine engine (30) and inside a nacelle (16), and fluid connections (32b) between the electrical motor (32a) and a generator oil system (32c). The generator oil system (32c) is offset from the electrical motor (32a) such that the generator oil system (32c) is not located radially outward of the electrical motor (32a) and inside the nacelle (16).
